President Volodymyr Zelensky announced Friday, July 31 that he held a “positive” phone call with US Vice President JD Vance, just hours after US President Donald Trump cast doubt on his previous decision to grant Ukraine a license to manufacture Patriot missiles domestically. Zelensky detailed the call in a statement on Telegram, describing the session as “productive.”JOIN US ON TELEGRAMFollow our coverage of the war on the @Kyivpost_official. According to the president, the discussion focused on his July 28 meeting with Trump in Washington, as well as securing the much needed Patriot interceptors – the only weapons capable of intercepting ballistic missiles. “Russian air strikes on our country are not letting up,” Zelensky said, adding that “air defense... remains a top priority.” In recent months, Zelensky has repeatedly appealed to allied partners for Patriot systems, as Ukraine continues to face a critical shortage, while Russia continues its near-daily bombardment nationwide. Trump’s changing diplomatic stance The call comes as Trump’s previous stance on Patriot productions has taken a different turn, just days after the two leaders met. In a phone interview with the Financial Times on Thursday, Trump said he was “not sure” whether the US would grant Ukraine the license to produce the missiles. “We’re looking at it,” Trump said. “It’s a very extraordinary weapon, and we have to be a little careful about who we license it to. We don’t really license equipment,” he continued.
